DRIVING-BELT.

Specification of Letters Patent.

Original application filed April 22, 1909, Serial No. 491,574. Dividedand this application filed July 26,

Serial No. 640,612.

To all whom it may concern:

Be it known that we, HENRY G. VoIGI-iT and AUGUST Vororrr, citizens ofthe United States, residing at New Britain, county of Hartford, State ofConnecticut, have invented certain new and useful Improvements inDriving-Belts, of which the following is a full, clear, and exactdescription.

This invention relates to improvements in driving belts, and is adivision from our copending application Serial No. 491,574, filed April22, 1909.

The object of the invention, broadly speaking, is to provide a durable,effective and safe driving belt at a minimum of expense.

In the drawings Figure 1 is a plan view of two ends of a belt showing aline of connection. Fig. 2 is an end elevation of one end of the belt.Fig. 3 is a section on the line ww Fig. 1, said view being relativelyenlarged.

The body of the belt proper is made of thin flexible steel, a stock of.012 to .015 of an inch being satisfactory for some purposes. The twoends of the main body of the belt are indicated at 1-1. Each edge of thebelt is rolled up or folded back upon itself, as shown, to afford borderreinforcements 2-2, which reinforcements perform several functions; forexample, by folding the belt at its opposite edges to form thereinforcements 22 danger of tearing the stock at the edges is greatlyreduced. Then again, by folding the edges of the belt upon themselves toform said border reinforcements, a smooth non-cutting edge is provided,greatly reducing the danger of personal injury should a workman come incontact with the belt. It will further be found that by providing theborder reinforcements aforesaid the belt will track or guide much moreaccurately on a pulley than were the border reinforcements omitted.

3 represents a bridging strip constituting part of the connection forthe two belt ends. As shown in the drawings, this brid ing strip iscountersunk, as at 3 3 the material of the belt ends 11 adjacent theretobeing forced into the countersunk portions by the heads 4& of rivets 1.

5-5 represent washers which surround the rivets 4 l and on top of whichthe outer ends L P of said rivets bear when said rivets are upset orswaged. In this par- ,ticular case the invention relates to the beltconstruction rather than to the method of connecting the ends. Bypreference the folded reinforcements 22 are pressed tightly down againstthe upper surface of the main body of the belt, and in running, suchfolds are preferably located on the outer side so as not to come incontact with the pulleys (not shown).

What we claim is:

1. A driving belt having its main body comprising a flexible metal stripwith each opposite edge thereof reinforced or thickened, eachreinforcement comprising a portion of the belt folded back upon itself.

2. A driving belt having its main body comprising a flexible metal stripand having a thickened border reinforcement along each edge thereof.
